Ubuntu has a feature of auto shutdown whenever it exceeds a temperature above 70 degrees Celsius. Is there any way to control this feature or prompt before the shut down?

    I don't think this a feature of Ubuntu, but one of your chipset configured through BIOS, and you don't actually want to shut it off, because it saves your machine from heat death. What you may want, is a warning, when your system gets close to that threshold, so you can save your work and shut it down properly. You may also want to investigate methods, that keep you machine cool (remove dust, replace CPU thermal conductor, increase internal and/or external air flow, use more hardware acceleration). – David Foerster Apr 04 '15 at 20:20
  • I just want to be notified before the auto shut down so that i can save my work and shut down properly. Now I can see my system's core temperatures and other parametres using acpi -V command as answered by @UTF-8. Is there any script or tool that 'll prompt me as soon as the critical temperature is reached ? – Rakesh Apr 05 '15 at 04:11
  • That would be a different question. Please find a similar one or open your own. I also suggest, that you take a look at your BIOS configuration options. Many mainboards have BIOS features for thermal warnings and shutdowns. – David Foerster Apr 05 '15 at 11:02

@UTF-8's answer doesn't work on ubuntu 20.04. Afer encountering the same problem I found the solution that works is to add thermal.crt=190 to the GRUB_CMDLINE_LINUX_DEFAULT option in /etc/default/grub.cfg. setting the critical CPU temp to 190C instead of the 100C limit set by ubuntu.

Here is a resolution:

Edit => /etc/default/grub

Edit => GRUB_CMDLINE_LINUX_DEFAULT=

Add => GRUB_CMDLINE_LINUX_DEFAULT="quiet splash thermal.nocrt=1"

Update GRUB => sudo update-grub

View settings, should be disabled => cat /proc/acpi/thermal_zone/THM/trip_points

View temperature => acpi -V or sensors

However, doing this comes at an obvious risk, whereas getting rid of dust in your PC comes at a much lower risk. Plus, it can be that not Ubuntu but your bios shuts your PC down which means that Ubuntu is the wrong place to change settings.
